Know therefore that the Lord your God, He is God, the faithful God, who keeps His covenant and His lovingkindness to a thousandth generation with those who love Him and keep His commandments;

Deuteronomy 7:9, NASB

This is some serious clique-making! Ynlikely, you think? This sour grapes eating should not affect the children, according to a late proverb, but here we have God keeping covenant and loving kindness for a thousand generations, but with strings. All those succeeding generations have no credit for themselves, but are the beneficiaries because of something an ancestor did. That is utterly opposite to the kingdom of grace and even contrary to the operation of the Sinai covenant itself with its Tabernacle services and atonement. Unlikely and never did happen. 

Never did happen

How do I know?  The Tabernacle stood for thousands of years until the temple was destroyed (2600 and 1950 years ago). If there is a temple service in operation today in 2022 it is the best kept secret of all religious activities. God appears to be rewarding covenant violation, but what is really happening is divine favour and faithfulness to Abraham.
